Me too, I noticed this for the first time. Never before ...
Last milestone of social endeavor for children does not end New Year's resolution
1. On New Year's Eve in a bar, no new adult friendships are counted in the final milestone of child social care.
2. The next day - somewhere in a park - finally new friendships to adults are counted in the last milestone of the social endeavor for children. However, the completion of the final milestone is not counted for the New Year's resolution to complete a milestone.
So many mistakes in Sim 4. Every ten minutes of gaming I see a new mistake. Something was forgotten in programming here and something there ... .
I have never Mods or CC, clean all days the caches in the user folder or make a new one, repair the game often, but - the mistakes are still there.
In the meantime, I am afraid of any revision of things that have ever worked. It's getting more and more worse.
PS: I choosed a new Aspiration, but still the same mistake. You can't finish this silvester goal no longer. I think, I remember that ist was possible - in earlier time. Again something, what does not functionate any longer in Sims 4. It becomes more and more less functionable.
I’m having this exact problem with a human sim doing the Strangerville Mystery. I might see if this Is aspiration-specific; maybe only base game aspirations work?.
Can't be the base game aspirations that work, because I just found this thread having the same bug with Collector aspiration. I had two sims resolve to lose weight, and it appears to have worked for one and not the other. I've never installed mods or cc. Quite disappointing to achieve a resolution and then not have it counted, in fact get a bad moodlet for it!
Update: I found a workaround to fix the issue. Another year passed, and I had the same problem again, but noticed it's only affecting the resolutions that have to do with aspiration milestones. If you change aspirations and THEN hit a milestone, you will get your resolution finished. I know that may be annoying, but it did work fo rme.
NONE of the resolutions are working for me now. ><
It might be related to the 'whims not fulfilling' bug, thinking about it.
